Cosmic ray imaging is a technology for nondestructive visualization of the interior of objects using cosmic ray muons. As its detector, Nuclear Emulsion, which record passing cosmic rays as tracks, are employed. One of the issues with Nuclear Emulsion is "latent image fading", where recorded cosmic-ray tracks disappear under high-temperature environments, and the occurrence of "Fog". This study attempted to suppress "latent image fading" using insulating materials and to suppress "Fog increase" by using a new additive compound.
